Study on Treatment of Fin Rot in Cultured Puntius sophore (Ham.) Using Extract of Neem (Azadirachta indica) Leaves

Traditionally fish farmers are known to use neem (Azadirachta indica) leaves in treating fn rot diseases. The present work intends to verify the effcacy of this age old practice of the fsh farmers. The diseased Puntius sophore fsh were treated with different concentration (0.5ml/l to 3.5ml/l) of neem leaves extract in increasing array (i.e., 0.5ml/l, 1.0ml/l, 1.5ml/l, 2.0ml/l, 2.5ml/l, 3.0ml/l and then 3.5ml/l sequentially) at an interval of 24 hrs. The fsh under treatment show improvement but the best result is observed where fsh are treated with the dose of 3 ml/l for a period of one day. The present fnding validates the usefulness of application of neem leaves in treating fn rot disease of fshes by the fsh farmers.
